Find three rational numbers between 3.1415 and 3.1416.

Given,

Two rational numbers : 3.1415 and 3.1416.

To find rational numbers between them, we extend the decimal places.

⇒ 3.1415 = 3.14150

⇒ 3.1416 = 3.14160

Three rational numbers strictly between 3.14150 and 3.14160 are :

⇒ 3.14151, 3.14152, 3.14153.

Hence, three rational numbers between 3.1415 and 3.1416 are 3.14151, 3.14152 and 3.14153.
